Ready for a handy office upgrade? Microsoft has introduced its Sculpt Ergonomic Keyboard, dubbed "the Manta Ray" because of its shape. The wireless accessory's split design boasts a cushioned palm rest, an attachable riser and the option to bundle with a separate numeric keypad and a mouse that's much more spherical than whatever is hovering under your hand right now.

So far, the Sculpt is earning favorable reviews: All Things D praises its thin and light design that effectively lessened wrist strain after a week of use, and Mashable says "preventing stress injuries never looked so good."

It's not often that the tech world gets this excited about, of all things, a keyboard. Then again, some keyboards are too unique to ignore.

Here's a look at seven of them.

Since the keyboard is entirely digital, any part of its surface can be programmed to perform specific functions (a touch color palette for graphic designers, for example) or even display images. The product received dismal reviews when released in 2007 and has since reverted to concept phase, but perhaps the tech world has come full circle now that mobile phone and tablet users are well-accustomed to touch keyboards.
